Its headquarters is located at 1 Whitehall Place, London, SW1A 2HD within the National Liberal Club. It was founded in Oxford in 1947, and has become the pre-eminent network for liberal parties and for the strengthening of liberalism around the world. The Oxford Manifesto describes the basic political principles of the Liberal International.

to win general acceptance of Liberal principles which are international in their nature throughout the world, and to foster the growth of a free society based on personal liberty, personal responsibility and social justice, and to provide the means of co-operation and interchange of information between the member organisations, and between men and women of all countries who accept these principles.

The aims of Liberal International are also set out in a series of seven manifestos, written between 1946 and 1997 and are furthered by a variety of bodies including a near yearly conference for liberal parties and individuals from around the world.[1]

Fifty years on, in 1997, Liberal International returned to Oxford and issued a supplement to the original manifesto, The Liberal Agenda for the 21st century, describing Liberal policies in greater detail. The second Oxford Manifesto was adopted by the 48th Congress of Liberal International, which was held on 27–30 November 1997 in the Oxford Town Hall.[4]
